Custom tag attributes and rtexprvalue property

Question

I have created a custom tag. In my .tld file I have added <rtexprvalue>true</rtexprvalue>
for several of the tag's attributes. Now I want to be able to pass values to
these attributes with the expression syntax:
eg <mytagprefix:pager maxRecordCount="{pageFlow.maxRecords}" />
where maxRecords is a public variable in my pageflow.
In my tag code to assign the value of maxRecordCount I have the following:
public void setMaxRecordCount(String maxRecordCount) throws JspException
Object obj = null;
obj = evaluateExpression(maxRecordCount, "maxRecordCount");
if(hasErrors())
reportErrors();
localRelease();
else
pb.setMaxRecordCount(new Long(((String) obj)).longValue());
I keep getting compile time errors in my jsp such as:
Error: no match was found for method setMaxRecordCount(long) in type package.PagerTag.
where package is the package of my custom class PagerTag.
In my pageflow maxRecordCount is a String. I don't understand why it is looking
for a long. Sometimes the error goes away and I thought I had gotten it to work
but then I realized that it was only working as long as the name of my attribute
and the name of my public variable matched and that is not what I wanted to do.
Should I be able to do what I am doing? I can instead pass this to the tag:
<netui-data:getData resultId="maxreccount" value="{pageFlow.maxRecordCount}" />
maxRecordCount="<%=(String) pageContext.getAttribute(\"maxreccount\")%>"
but that is much less convenient.
Thanks for any help.

Hello,
Yes I forgot to include the faces xml DD. Here are the portions of code relating to the component and renderers:
<render-kit>
<renderer>
<component-family>MyFamily</component-family>
<renderer-type>MyRenderer</renderer-type>
<renderer-class>essaisUn.MyRenderer</renderer-class>
</renderer>
</render-kit>
<component>
<component-type>MyComponent</component-type>
<component-class>essaisUn.MyComponent</component-class>
<component-extension>
<component-family>MyFamily</component-family>
<renderer-type>MyRenderer</renderer-type>
</component-extension>
</component>I changed from "<hello>" to "hello" and I still get the same exception.
Can anyone bail me out?
Thanks in advance,
Julien Martin.
